Abstract
The utility model relates to a kind of sealing device for roller mill separator, comprise powder concentrator (1) and be positioned at the rotating vane (5) of powder concentrator, on described powder concentrator inwall successively affixed first buffering block (7), the first fixing seal block (2) and the second fixing seal block (3), the end of described blade is longitudinally installed with rotatory sealing block (4), and described rotatory sealing block is between the first fixing seal block and the second fixing seal block.The affixed buffer film in the surface (7a) of described first buffering block.Affixed second buffering block (6) in lower end of described first fixing seal block.The utility model improves the sealing property of roller mill separator, extends the service life of seal.
Description
Technical field
The utility model relates to the sealing device for roller mill separator, belongs to Vertical Mill and selects powder equipment technical field of sealing technology.
Background technology
In vertical mill system, powder concentrator is arranged on directly over Vertical Mill main equipment as material screening device, carries out the screening to material after grinding completes, and by self High Rotation Speed of powder concentrator, distinguishes the qualified and underproof product of setting.Due to roller mill separator, place in start process runs up, rotating speed reaches as high as 1000rpm, in Vertical Mill process system, under whole process is in negative pressure state, material forms rapid movement when negative pressure, material is in by powder concentrator, the wearing and tearing caused sealing station are larger, when sealing wear, powder concentrator loses the ability of material screening gradually, material just directly can be pass by from this position, has skipped the position of powder concentrator screening, like this just loses meaning and the function of powder concentrator existence.Qualified and non-qualified material all can be regarded as finished product and carry out follow-up collection and process.The serious quality affecting material.
Because powder concentrator is slewing, cannot use fixed sealing original paper in the sealing of position of rotation, as outside framework oil seal or O type circle etc., therefore, the problem that roller mill separator sealing is poor and service life is short is not resolved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of sealing device for roller mill separator, and structure is simple and have good sealing property.
The technical scheme that the utility model solves the problem is as follows:
A kind of sealing device for roller mill separator, comprise powder concentrator and the rotating vane being positioned at powder concentrator, on described powder concentrator inwall successively affixed first buffering block, the first fixing seal block and the second fixing seal block, it is characterized in that:
The end of described blade is longitudinally installed with rotatory sealing block, and described rotatory sealing block is between the first fixing seal block and the second fixing seal block.
Further, the affixed buffer film in surface of described first buffering block.
Further again, the affixed second buffering block in lower end of described first fixing seal block.
Further, the position of block is cushioned in the lower end of described second buffering block lower than first.
Operation principle of the present utility model and beneficial effect are that particulate dust, when the sealing station impacting powder concentrator, first collides the first buffering block, reduces the speed of service, decrease the effect of attrition to subsequent parts.Material after deceleration, due to the impact of negative pressure, still sealing position can be entered, but in powder concentrator place runs up, between the first fixing seal block and rotatory sealing block, form malleation air-flow, stop that material enters, the wearing and tearing of the first fixing seal block are strengthened gradually, after the first fixing seal block is worn, the second buffering block is thereunder installed, extended its service life.If the second buffering block is worn, for anti-material passes through, the second fixing seal block and rotatory sealing block form malleation air-flow again, because this position has been in last sealing together, and the inspection regular according to scene.Equipment side can be allowed to have time enough to prepare spare part change.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail; the restriction of described embodiment not to utility model protection scope; obviously; those of ordinary skill in the art are not needing to obtain other embodiments under the prerequisite paying creative work, and these all belong to protection domain of the present utility model.
Shown in composition graphs 1, a kind of sealing device for roller mill separator, comprise powder concentrator 1 and be positioned at the rotating vane 5 of powder concentrator, on described powder concentrator inwall successively affixed first buffering block 7, first fixing seal block 2 and the second fixing seal block 3
The end of described blade is longitudinally installed with rotatory sealing block 4, and described rotatory sealing block is between the first fixing seal block and the second fixing seal block.In order to reduce the speed of material further, at the affixed buffer film 7a in surface of the first buffering block.
The affixed second buffering block 6 in lower end of described first fixing seal block.The position of block is cushioned in the lower end of described second buffering block lower than first.
Operation principle of the present utility model is, particulate dust is when the sealing station impacting powder concentrator, first the first buffering block is collided, reduce the speed of operation, material after deceleration, due to the impact of negative pressure, still sealing position can be entered, but in powder concentrator place runs up, form malleation air-flow between first fixing seal block and rotatory sealing block, stop that material enters, the wearing and tearing of the first fixing seal block are strengthened gradually, in order to avoid the first fixing seal block is worn, the second buffering block is thereunder installed.If the second buffering block is worn, for anti-material passes through, the second fixing seal block and rotatory sealing block form malleation air-flow again, because this position has been in last sealing together, and the inspection regular according to scene.Equipment side can be allowed to have time enough to prepare spare part change.
